Answer:
P = 8.5 x + 3 ft
Step-by-step explanation:
To find the perimeter, we use the formula
P =2(l+w) where l is the length and w is the width
P =2 (1.25x+3 + 3x-1.5)
Combine like terms
P = 2( 4.25x +1.5)
Distribute the 2
P = 8.5 x + 3 ft

Answer:
Step-by-step explanation:
Given that:
Population Mean = 7.1
sample size = 24
Sample mean = 7.3
Standard deviation = 1.0
Level of significance = 0.025
The null hypothesis:

The alternative hypothesis:

This test is right-tailed.

Rejection region: at ∝ = 0.025 and df of 23, the critical value of the right-tailed test 
The test statistics can be computed as:



t = 0.980
Decision rule:
Since the calculated value of t is lesser than, i.e t = 0.980 <
, then we do not reject the null hypothesis.
Conclusion:
We conclude that there is insufficient evidence to claim that the population mean is greater than 7.1 at 0.025 level of significance.
